3.2 Software architecture
The KeContact M10 system contains the following main software components.
Load Manager:
The load manager has the following responsibilities:
 Controls and coordinates charging sessions for several vehicles on the separate charging stations
(PDCs).
 Is offering WEB services for the vehicle manager. These services allow the vehicle manager to initi-
ate, start / stop charging sessions and other activities in response to the according requests of an
electric vehicle using high-level communication.
 All necessary activities and events that occur on the different charging stations (sockets) are man-
aged and controlled by the socket manager (PDC manager). This way the socket manager assists
the load manager in managing the separate charging sessions.
 The load manager gathers the different information of the separate charging sessions, the used
PDCs and the vehicle information and forwards those data to the charge point manager.
A core component of the load manager is the socket manager:
 Represents the network of all connected PDCs and their status.
 Forwards requests to the addressed PDCs, handles and reports status changes
Vehicle Manager:
The vehicle manager has the following responsibilities:
 Handles communication with vehicles using high-level communication (ISO 15118). Issues requests
to the charge point manager and web service requests to the load manager in order to fulfil loading
requests received by vehicles.
 Establishes und closes secure communication sessions with vehicles.
Charge Point Manager:
The charge point manager has the following responsibilities:
 Manages the available power and assigns it to the PDCs (for Mode 3 charging) and to electric vehi-
cles (for charging controlled by high-level communication).
 Manages the HTML user interface for monitoring (status and current transactions) and entry of con-
figuration data. Access to the monitoring pages of the charge point manager is allowed to anybody
with proper network access.
 Pages for configuration and system changes require a login.
User Interface:
The operator of the system connects with a web browser to the KeContact M10.
